SEPARABLE HINGE.

SPECIFICATION forming part of Letters Patent No. 682,071, dated September 3, 1901. Application filed January 7,1901. Serialll'o. d2,3'77. (No model.)

T0 at], whom, it nutty concern:

Beitknown that I, CHARLES HARTMANN, a citizen of the United States, residing in and whose post-office address is the city of Ohicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Separable Hinges for Timdows, Doors, and Similar Devices, of which the following is a specification.

My invention relates to separable hinges for windows, doors, and similar devices, and it particularly relates to means forad j ustably and removably hinging or hanging such devices in place.

Its object is to provide a hinge simple and effective in operation and of comparatively small cost and which shall possess the advantageous characteristics hereinafter to be referred to; and to those ends it consists in the features of construction and combination to be hereinafter more particularly described, and pointed out in the claims hereto annexed, reference being had to the accompanying drawings, wherein like reference-letters indicate the same or corresponding part-s.

Figurel is afront elevation ofa full-length window equipped with my device. Fig. 2 is a sectional view and shows the relative position of the parts of the hinge of my invention when the same is in its closed position. Fig. 3 is in part a plan and in part a perspective view of the hinge of my invention, the hingepin being shown in plan view and the hinge proper in perspective. Figs. 4, 5, 6, and 7 are vertical sections taken on the line 00 5c of Fig. 1, to be hereinafter more fully described. Fig. 8 illustrates a modified form of my invention. Fig. 9is ahorizontal section taken on the line 9 9 of Fig.8. Fig. 10 is a perspective View and represents a modified form of the hinge proper of my invention.

I am well aware that hinged windows and hinged storm-windows are old in the art, and I am further aware that it is old in the art to so hinge said-windows that they may be swung outwardly and upwardly or opened in the manner of a door, and it will therefore be understood that I do not mean my invention to broadly cover such hinging.

Heretofore it hasbeen necessary for the operator in hanging storm-windows or similar devices to perform the work from without the building, which frequently necessitates the employment of one or more step-laddersand a helper. By employing the device of my invention, as will presently appear, the disadvantages of the devices now known in the art are removed and the windows may be adjusted in position and removed therefrom, said action being performed from within the building, and except in very rare cases,where the window is of unusual weight, even a fulllength window may be readily adjusted in place or removed therefrom by a single person.

For the sake of brevity I will describe the operation of my device in connection with its use on full-length windows, it being understood-that it may be employed as well upon screens and doors of all kinds and sizes and upon other devices desired to be hinged.

Referring to the drawings, A is a windowframe; B, a lintel; O, a hinge-pin; D, a hingeplate, forming one member of the hinge, and is preferably formed of a piece of spring metal and bent in substantially a V shape, the arm 61 thereof being provided with a curved portion adapted, in connection with the arm d, to engage the hinge-pin 0, when the thumb-screw d is screwed upon the threaded draw-pin d in such manner that the base d of the thumb-screw bears against the frame A or a plate a, provided for that purpose, and d a suitable screw or rivet hole. It will be seen that the draw-pind in addition to the screw d serves to secure this portion of my device to the window-frame, while it is obvious that additional means may be employed to that end, if desired. The closed position of the parts of this form of my device is best illustrated in Fig. 2 of the drawings, while Fig. 8 illustrates the closed position of a modified form of my device, which form will be hereinafter described.

It will be observed that when the thumbscrew is screwed out upon the draw-pin the arm at will spring away from the arm (1 and assume its normal position, as shown in Figs. 4, 5,'and 6.

Assuming the window to be in place and the arms d d ofthe hinge engaging the pin 0, as shown in Fig. 2, to remove the window it is but necessary to screw back the thumbscrew (1 in such manner that the arm 01 will .9, provided for that purpose.

be sprung away from the arm d and assume the position shown in Fig. 4, following which the window may be pushed forward upon the sill sufficiently to admit of the hands grasp:

eye 6, which means, assisted by the arm d of the hinge, which is still in engagement with the hinge-pin C, will prevent the accidental dislodgment of the window when the thumbscrew is turned as described.

To adjust the window into position, it is but necessary to reverse the above-described operation-that is, to rest the window-frame against the customary guide-strip F, as shown time drawing it inwardly at the bottom, the continuation of which operation will result in the arm d engaging the hinge-pin O, as shown in Fig. 6, following which the lower end of the window may be fastened by the hook E, and thereafter the thumb-screw d be turned in such manner as to cause the arm d to engage the hinge-pin O, as shown in Fig. 7. When this operation has been performed, it will be observed that the window will be hinged and may be outwardly opened to such an extent as desired. Any of the well-known means may be employed to retain it in open or closed position.

Referring to the modified form of my device, (shown in Figs. 8 and 9,) G is a lever enlarged and provided with the eccentric groove g, which groove is adapted to engage the end of the draw-pin 61 as shown in Fig. In operating the lever G the cam-operating groove will control the action of the draw-pin d either to draw the arm d toward the arm d or to thrust it outwardly and away from said arm. Where I employ this form of my device, I prefer that the draw-pin and the controlling groove shall be at dead-center with the fulcrum-point g when the hinge is in its closed position, thus constituting a self-locking def invention may be positioned at any desired point upon a window, door, or other article desired to be hinged and that the arms d d need not be formed of the same piece of metal, but may be constructed in any suitable manner-as, for instance, that shown in Fig. 10. It will also be understood that whereas I have shown my device secured to a windowframe and lintel by screws any suitable securing means may be employed in their place, which means may extend through the frame and be secured on the innersideas, for example, rivets, bolts, and nuts or similar devices-and it will be further understood that the number, size, and form of the parts of my device may be greatly varied without departing from the principle'of'the invention.

Having thus described myinvention, what i I claim as new, and desire to secure by Letters Patent, is in Fig. 5, and push it upward, at the same j l. The combination with a window frame and sash, of a hinge-pin carried by the said frame, a movable member carried by the sash and having a bearing at its upper end, and 1 means for locking said bearing on said hingef pin, substantially as described.

2. In a hinge, the combination with a hingepin, of a V-shaped member, the outer arm of said member having an inwardly-open con- ;caved bearing adapted to receive the said hinge-pin, means for securing the lower end i of said member to the device to be hinged, a bolt passing through both arms of said mem- -l her and means carried by the bolt for drawing the two arms together whereby said concave bearing is held in engagement with the i hinge-pin, substantially as described. pivoted at the point 9, its pivoted end being 3. The combination with a window frame and sash, of a hinge-pin carried by the upper portion of said frame, a plate secured to the upper end of the sash and extending thereabove, a movable member carried by the plate and having an inwardly-open concaved bearing adjacent the upper end of said plate and adapted to receive the hingepin, and means for drawing said bearing around the hinge-pin and against said plate and locking it, substantially as described.
